It's purely a module, and can be built with the kernel headers
installed.

OK that seems reasonable.

I can manage that OK too :)

I'll take a look at it..

I guess it's a simple matter of testing it and seeing what happens.

In general I stick to stock kernels. On a few machines I've had to
rebuild the image from source with a couple of patches. (I have a
machine with a webcam on it that I got working by patching the pwc.o
file directly too - but we'll pretend I'd never do that ;)
I think that I should be able to do what you suggest, make a source
package and also make an image for the kernel(s) that I intend to use
this on.
If I get the chance I'll make a modules/tpe archive too - but I think
that I don't need to do that just yet.
Thanks for the comments.
